System A 160 CLOCK DIVIDER gt Trig 2 In Res In e o 4 2 A 100 Clock Divider A 160 1 Introduction Module A 160 Clock Divider is a frequency divider for clock signals designed to be a source of lower frequencies particularly for rhythm uses The Trigger input will take clock signals from eg an LFO MIDI sync or the gate from a MIDI CV interface At the outputs you have access to the sub divided clock signals from half the clock frequency down to 1 64 The A 160 also has a reset input Whenever a reset signal is sensed all outputs are set to zero until the reset voltage disappears The Clock Divider can be used in combination with the A 161 Clock Sequencer to produce stepped sequen ces with a length of from one to eight events A 160 Clock Divider 2 Overview 1771 A 160 CLOCK DIVIDER Trig amp In O Res In O eo 12 0 14 eo 18 116 gt 132 164 LIL System A 100 Indicators O LED LED LED O LED LED LED In Outputs O Trig In Res In 12 14 18 116 132 164 00000000 Clock 2 indicator Clock 4 indicator Clock 8 indicator Clock 16 indicator Clock 32 indicator Clock 64 indicator clock signal input reset input 1 2 clock frequency output 1 4 clock frequency output 1 8 clock frequency output 1 16 clock frequency output 1 32 clock frequency output 1 64 cloc2. f four output O The original whole LFO oscillation is patched to the re trigger input on the ADSR In this way a new repeating envelope is created A 160 Clock Divider System A 100 vo1 on A 131 G Audio 102 i Out Gate cv KA Out i R Fig 1 Ping Pong effect LFO Fig 2 ADSR envelope with retriggering Tej By using different outputs on the A 160 it s possible to have envelopes re triggering dif ferent numbers of times from two to thirty two In addition by using an A 161 3 5 6 or 7 step triggering is possible as well You patch the A 161 s O or output to the gate input of the ADSR Output or O is patched to the A 160 s reset input socket Other suggestions for using the A 160 are in the A 161 Clock Sequencer s section of the manual DUEPFER System A 100 Clock Divider A 160 A 160 Clock Divider System A 100 DOEPFER 6 Patch Sheet The following diagrams of the module can help you recall your own Patches They re designed so that a A 160 A 160 A 160 complete 19 rack of modules will fit onto an A4 Es a sheet of paper Trig Trig Tris Photocopy this page and cut out the pictures of this Res Res 9 Res and your other modules You can then stick them E je pe onto another piece of paper and create a diagram of e He se your own system 12 E Le 0 0 e Make m
